 I've been working on this test on and off for an hour now... I'm done with all but 2. Jesus.
Ha.. I think I spent 10-20 minutes on this. I just put random answers for 2, the spring one and the satellite one. I don't know what the third one I got wrong was though.

EDIT: I guessed on the spring question because I couldn't understand it now matter how many times I re-read it. I solved the sattelite one (probably incorrectly, as my first answer said 12 hours).
I simply didn't understand the phrasing of the two. For the satellite one, I made a somewhat thought out guess of 24, because it took 8 hours to orbit around the moon, so 3 times would be 24 hours. I knew it was too simple an answer, but couldn't really figure out what they meant.

I knew it was too simple an answer, but couldn't really figure out what they meant.
My guess went something like this: A circle will have 4 points on it, A B C D, counter clockwise. One 360 orbit takes 8 hours. That means it takes 2 hours for each quadrant (right? Because there are 4 quadrants... or is it 4/3 of an hour? I need to understand what they meant by orbit.) Starting at point A (one passover), you'll travel for 8 hours until you hit point A again (second passover). You then backtrack one quadrant to D, which takes 2 hours. You then go forwards again one quadrant which takes another 2 hours, hitting A again, and completing the third passover. Total time: 12 hours. I don't know if the "orbit time" was the time to get from point A back to point A BEFORE or AFTER the backtracking? I also don't know what counts as a passover. Does the inital spot not count? These unanswered questions would have helped me figure out the answer to that one. 
Oh, each orbit included backtracking? I see. Your problem, then, would be not multiplying 12 by 3. It would take 12 hours for one orbit, not three.

Well, the way I figured it out was to determine the travel time for each quadrant. If the 8 hours was including the backtracking, then it would have been FIVE total quadrants in the cycle, not 4, changing my travel time to 8/5 instead of 8/4. I don't think it did, but still... it wasn't specified. It also didn't specify what counted as a passover, so that left some guessing there. After I struggled with not getting any of the multiple choices for a while, I just guessed 24 hours, which was my hope that only my assumption of what counted as the first passover was incorrect. It turns out both the first and the second were incorrect. Oh well, I tried my best, and considering I haven't done any math in a long time, I'm surprised I figured any of it out. =D

With that, my friend, you made the problem much more complicated than it needed to be. Your quadrant circle method worked just fine. The satellite orbits once, backtracks a quarter of the moon, goes forward and is at the same spot before it backtracked. 12 hours have passed, repeat twice. Doesn't sound too complicated to me.

Oh well, I tend to do that a lot. I break it up in to steps to make it easier to solve, and so I can double check my work. However, your method doesn't work either, because remember: the new rotation starts one quadrant EARLIER than the previous one. So, in other words, it goes like so: [A B C D C] [D A B C B] [C D A B A] and so on. It's not going to backtrack one quarter and then go forward that quarter before starting a full 360 degree rotation! The entire process is set back one quarter each time it happens, so I broke it up in to parts to try to fix that. Obviously, it didn't work, and your method might have gotten the correct answer... but would it have been the right method?

Ah. I keep reading it wrong. It wasn't even my method, it was an interpretation of yours. I don't really know, I think I'm going to look back at those problems tomorrow when I've slept fully and figure them out.
